Abstract

A stair handrail mounting bracket facilitates the installation of handrails, the bracket including a series of elements that make it, mechanically, a fixed support of the handrail anchored to the nosing of the steps, allowing the automatic and uniform positioning at a level of the handrail for the whole length of the stairs before it is fixed to the wall. The mounting bracket includes two support bases, a system of clamping elements including a clamp provided with a threaded bar that can be adjusted via a nylon knob. The nylon know allows the tightening or loosening of the support that anchors the bracket support bases to the stair step nosing. The bracket support bases includes two sliding tracks on which to slide a support bar that can be locked in place as required with two geared knobs.

Description

Field of invention

The present invention relates to a bracket whose component parts facilitate the installation of stair handrails because they allow the worker to keep the handrail mechanically fixed to the stair steps before it is fixed to the load-bearing wall so as to guarantee the automatic and uniform positioning of the handrail at level for the whole length of the stairs.

Background

Currently, installation of stair handrails is carried out manually and needs to be done by several workers whose number is proportional to the length of the stairs.
In particular, today it is particularly difficult to position the handrail at a uniform level for the whole length of the stairs.
The relevant background art, useful to understand the subject-matter of the present invention has been disclosed in the following documents:

D1: No. DE 10 2004 055818 Al published on 01/06/2006 ;
D2: No. US 5 527 016 A published on 18/06/1996 ;
D3: No. US 4 669 577 A published on 02/06/1987 ;
D4: No. EP 0 288 100 A published on 26/10/1988 .

D1 discloses a mounting device with a bearing which is fixable in a form-locking way to a railing and, connectable to said bearing, a length-adjustable supporting device which may be connected directly or indirectly to the bearing and a support bearing which is supportable directly or indirectly against a building part. The support bearing has a receiving device for a holder element and may be connected in a form-locking way to a building part via holder element.
D2 discloses an apparatus for accurately positioning a stairway handrail in an inclined position. The apparatus may include two vertically adjustable stanchions positionable at the upper and lower ends of the stairway. Miniature platforms are tiltably mounted on the upper end portions of the stanchions to underlie end areas of a handrail; C-clamps may be used to clamp the handrail to the platforms.
D3 discloses a clamping-type guard rail support having a post which is clamped in position by raising an opposing clamping arm attached to a threaded rod which is braced to prevent rotation of the rod and arm.
D4 discloses a support for the handrail of a detachable handrail assembly, with a base kept in place by a weight and a post which is connected thereto and to which the handrail can be fixed, in which the bottom end of the post lies a distance above the bearing face of the base, base and post are interconnected by means of a horizontal hinge situated at a distance above said bearing face, and means are provided for locking the base and post relative to each other when in the folded-out position.
The problem to be solved by the present invention with respect to D1, that is deemed to be the closest prior art, may be regarded as:

= providing an adjustment means for the clamp;
= making the fixation of the support bases to the panel more flexible in its location along the panel.

Disclosure of invention

It is an object of the present invention to provide users with a handy, light and inexpensive bracket that will make it easier to install a stair handrail with the prior mechanical locking of the handrail to the stair steps before it is fixed to the load-bearing wall so as to facilitate the automatic and uniform positioning of the handrail at level for the whole length of the stairs.
It is another object of the present invention to provide workers with a simple, inexpensive tool that will eliminate the problems described above.
It is another object of the present invention to reduce the labour required so as to lower the cost of installing stair handrails and in any case to facilitate and improve their installation.
These and other objects are achieved by the stair handrail mounting bracket whose components mechanically define its function of fixed handrail support anchored to the nosing of the stair steps, that is, to their protruding part, before the handrail is fixed to the load-bearing wall, so as to facilitate the installation of the handrail and, in particular, its automatic and uniform positioning at level for the whole length of the stairs. For stair steps without nosing or steps that are rounded, and therefore such that the bracket cannot be anchored, the present invention has a variant whereby the prior fixing of the bracket to the step is brought about by a 20/25 kg weight provided by a pin that is inserted in the opposite end of the support bar on which the handrail support and locking base is mounted.

Detailed description

Other characteristics and advantages of the invention will become more readily apparent from the description of a preferred but not exclusive embodiment, of the invention illustrated by way of non-limiting example in the accompanying drawings, in which:

Fig. 1 is a view of the invention of the present application complete with all its functional parts;
Fig. 2 shows the two support bases of the system on the step;
Fig. 3 is a view of the clamp for clamping the support bases to the step;
Fig. 4 shows the support bar, which is preferably telescopic so that the bracket can also be adjusted according to the width of the stairs on which the handrail is to be installed;
Fig. 5 represents the handrail support base with its locking system;
Fig. 6 is a view of the invention with the variant envisaged in the case of steps without nosing or rounded steps.

The invention consists of a stair handrail mounting bracket made up of a system for mechanically fixing it to the stair steps consisting of two support bases (1) and (1/a) that are anchored to the nosing of the steps with a clamping clamp (2) provided with a threaded bar (3) that can be adjusted via a nylon knob (4) to allow tightening or loosening of the anchoring supports (5) and (5/a) on the stair step nosing. The support bases (1) and (1/a) have two sliding tracks (7) and (7/a) on which is inserted a support bar (6) that can be locked as required via two geared knobs (8) and (8/a). The support bar (6) is preferably telescopic so that the invention can also be adjusted according to the width of the stairs on which the handrail is to be installed.
A threaded bar (9) is welded on the outside of the bracket and its purpose is to support and adjust the support base of the handrail (10) both widthways and lengthways according to the pitch lines of the stairs so that, once the handrail has been placed at uniform level after being locked with a quick clamp (11), it can easily be fixed to the stair load-bearing wall.
In the case where the stairs have steps without nosing or with their final part rounded, the above described invention has the variant of replacing the above described fixing system with one of a 20/25 kg weight (12) provided by a pin (13) that is inserted inside the support bar (6). In this variant, the invention will have just one support base (1) on the step and it will be adjusted to the height of the step via the threaded bar (3) and the nylon knob (4).
